Oscillatory activity in the gamma-band range has been related both to gestalt perception and to cognitive functions such as attention, learning, and memory. After giving a brief account of recent findings from electroencephalography and intracortical recordings, the present review will focus on spectral activity in the magnetoencephalogram. Here, gamma-band effects are topographically more local and involve higher frequencies than in the electroencephalogram. Bottom-up-driven auditory spatial… Expand

Cortical oscillatory activity during spatial echoic memory
TLDR
Spatial echoic memory is performed by networks along the putative auditory dorsal stream, without requiring an involvement of prefrontal executive regions, according to the previous short‐term memory study. Expand
Cortical Oscillatory Activity and the Dynamics of Auditory Memory Processing
TLDR
Investigation of oscillatory signals in magnetoencephalogram (MEG) during different types of auditory processing found that oscillatory activity in MEG may provide unique information about both the activity of local networks and cortico-cortical integration. Expand
Gamma-band activity over early sensory areas predicts detection of changes in audiovisual speech stimuli
TLDR
Findings support the relevance of high-frequency oscillatory activity over early sensory areas for perceptual experience in human magneto- and electroencephalogram recordings. Expand
Frontal gamma-band activity in magnetoencephalogram during auditory oddball processing
TLDR
GBA was increased over left inferior frontal cortex, replicating previous results of putative auditory ventral stream activation during passive pattern deviance processing, and additional GBA enhancements over superior frontal cortex were specific to active target detection. Expand
Effects of memory load on cortical oscillatory activity during auditory pattern working memory
TLDR
The present magnetoencephalography study investigated memory load-dependent changes in cortical oscillatory activity during a modified auditory version of the Sternberg paradigm, demonstrating the relevance of both beta and alpha oscillations for the memorization of multiple stimuli. Expand
Let's talk together: memory traces revealed by cooperative activation in the cerebral cortex.
TLDR
This chapter provides an overview of magnetoencephalography studies of different types of memory processes and focuses on cortical oscillatory activity as a correlate of working memory. Expand
Sources of synchronized induced Gamma-Band responses during a simple object recognition task: A replication study in human MEG
Natural stimuli are compiled of numerous features, which are cortically represented in dispersed structures. Synchronized oscillations in the Gamma-Band (>30 Hz; induced Gamma-Band Responses, iGBRs),… Expand
Frontal midline theta rhythm and gamma power changes during focused attention on mental calculation: an MEG beamformer analysis
TLDR
Spatially filtered MEG and permutation analysis was used to precisely localize cortical generators of the magnetic counterpart of Fmθ, as well as other sources of oscillatory activity associated with mental calculation processing (i.e., arithmetic subtraction), confirming and extended earlier EEG/MEG studies indicating that Fm θ during mental calculation is generated in the dorsal anterior cingulate and adjacent medial prefrontal cortex.

Human gamma-frequency oscillations associated with attention and memory
TLDR
Recent findings demonstrating human gamma-frequency activity associated with attention and memory in both sensory and non-sensory areas are discussed. Expand
Multisensory processing and oscillatory gamma responses: effects of spatial selective attention
TLDR
An EEG study investigating the interactions between multisensory (audio-visual) integration and spatial attention, using oscillatory gamma-band responses (GBRs) found that attention particularly affects the integrative processing of audiovisual stimuli at these early latencies. Expand

Dynamics of gamma-band activity in human magnetoencephalogram during auditory pattern working memory
TLDR
The memorization of syllables was associated with synchronously oscillating networks both in frontotemporal cortex, supporting a role of these areas as parts of the putative auditory ventral stream, and in prefrontal, possible executive regions. Expand
Dynamics of Gamma-Band Activity during an Audiospatial Working Memory Task in Humans
TLDR
Gamma-band activity during the volume task may reflect auditory pattern encoding in auditory ventral stream areas and increased coupling between networks serving representation of audiospatial information and frontal executive systems seems to activate frontal and parietal neuronal ensembles.

TLDR
Results of the present experiments in combination with other studies presented in this volume are supportive for the notion that induced gamma band activity in the human EEG is closely related to visual information processing and attentional perceptual mechanisms. Expand
Functional mapping of human sensorimotor cortex with electrocorticographic spectral analysis. II. Event-related synchronization in the gamma band.
TLDR
Gamma ERS may provide complementary information about cortical neurophysiology that is useful for mapping brain function in humans, and maps of sensorimotor function inferred from gamma ERS were consistent with maps generated by cortical electrical stimulation for clinical purposes. Expand
Dynamics of gamma-band activity induced by auditory pattern changes in humans.
TLDR
The results support the hypothesized role of anterior temporal/ventral prefrontal regions in the processing of auditory pattern change and extend earlier findings of gamma-band activity over posterior parieto-temporal cortex during auditory spatial processing that supported the putative auditory dorsal stream.

Selective visual-spatial attention alters induced gamma band responses in the human EEG
TLDR
The rotating stimulus elicited higher gamma band power as compared to the standing stimulus at electrode locations, which may be related to the activity of underlying cortical structures specialized for motion processing. Expand
Human Gamma Band Activity and Perception of a Gestalt
TLDR
The topography of gamma band spectral power and event-related potentials in human EEG associated with perceptual switching effected by rotating ambiguous (bistable) figures support the notion that formation of a visual percept may involve oscillations in a distributed neuronal assembly. Expand
Induced electrocorticographic gamma activity during auditory perception
Abstract Objective : To define the spatial, temporal, and functional characteristics of induced gamma (>30 Hz) activity during functional activation of the left superior temporal gyrus. Methods :… Expand
Induced gamma-band activity during the delay of a visual short-term memory task in humans.
It has been hypothesized that visual objects could be represented in the brain by a distributed cell assembly synchronized on an oscillatory mode in the gamma-band (20-80 Hz). If this hypothesis is… Expand
Visually induced gamma‐band responses to coherent and incoherent motion: a replication study
